DEVICE FOR FORMING HEEL-CALKS ON HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 572,125, dated December1, 1896.

Application filed 'lune 15,1896. Serial No. 595,552. (No model.)

AT0 all U17/07u t 71am/ concern:

Be it known that I,PHILIP M.PRAMER,a citizen of the United States,residing at Clear Lake, in the county of Cerro Gordo and State of Iowa,have invented certain new and useful Improvements in a Device forForming I'Ieel-Calks on Horseshoes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in devices for forming heel-calkson horseshoes, the object of the same being to provide such a device bywhich heel-calks may be made without the use of a hammer or the strikingof a blow.

My improved device is made up of an upright, a supporting-bar pivotallyconnected thereto, means for clamping the horseshoe in the upper end ofsaid supporting-barupon the top and side thereof, a tool adapted to turnover or upset the end of the horseshoeblank, and means for drawing saidsupporting-bar toward said upright and bringing the end of the horseshoeinto engagement with the tool attached thereto.

The invention also consists of other details of construction andcombinations of parts, which will be hereinafter more fully describedand claimed.

In the drawings formingapart of this speciiication, Figure 1 representsa side elevation of my device. Fig. 2 is a similar view showing theparts in operative position. Fig. 3 is an end elevation. Fig. 4 is a topplan view. Fig. 5 is a vertical longitudinal section, and Fig. Grepresents details of the upsettingtools.

Like reference-numerals indicate like parts in the dierent views.

My improved device is made up of an upright or standard 1, rising from abase-plate 2, which is adapted to be secured to the floor or anystationary part of a building by lagscrews passing therethrough. Thestandard 1 is provided with ears 3 3, in which is pivoted asupporting-bar 4, having a slot 5 therein in which is located a spring6, upon which rests a foot-lever?, fulcrumed in the standard 1, asclearly shown.

Near the upper end of the standard 1 the attached to the upper end ofthe supporting,

bar 4. Surrounding the bolt 12 and bearing against the inner faces ofthe `standard and the supporting-bar 4 is a spiral spring 14,

which tends to hold said supporting-bar' normally in its outer position.Pivoted in a recess 15, near the upper end of said upright l, is anupsetting-00116, having a projection 17 upon its inner-surface, aroundwhich passes a spiral spring 18, which tends to urge the upper end ofsaid tool normally outward. The projection 17 on said tool is adapted tobear against the inner face of the standard 1 when the outer face ofsaid. tool is forced to a position in which it lies flush with the innersurface of said upright. The tool 16 acts in engagement with acorresponding tool or plate 19, secured to the inner surface of theupper end of the supporting-bar 4.

Fulcrumed in the ears or projections 2O 20, upon the side of thesupporting-bar 4, is a lever 21, which is pivoted to a slidingclamping-plate 22, moving in guides in the upper end of thesupporting-bar 4. Between the clamping-plate 22 and the upper projectingend 23 of said supporting-bar 4 a recess is formed, within whichthehorseshoe-blank 24,

tween the projecting end 23 and the sliding clamping-plate 22.

As thus constructed the operation of my i device is as follows: With theparts in the position in which they are shown in Fig. 1 the end of thehorseshoe-blank 24, after being heated, is inserted within the recessbetween the extension 23 and the clampingplate 22 and the lever 2 1drawn outwardly, thereby forcing said clamping-plate 22 inwardly andholding said horseshoe-blank firmly upon the two sides thereof. At thesame time the'foot-lever 7 is depressed,which throws down the rod 25 andforces the head 26 thereof into engagement with the surface of saidhorseshoe-blank,thereby clamping said blank upon its sides and top. Thelever 10 is then drawn to the right, and by reas-on of the engagement ofthe bifurcated ends 1l thereof with the nut 13 on the outer end of thebolt 12 the-said bar is thrown outwardly, drawing the supporting-bar atoward the upright l and bringing the projecting end of thehorseshoeblank 2a into contact with the angularly-disposedupsetting-tool 1G. Then this is done, the end of the blank 24 is turneddown by the tool 1G, and a further pressure on the lever 10 willcompress the spring 18, engaging the inn er face of the tool 16 and turnthe calli formed on the blank 24 down at right angles thereto. The partsmay then be released and will fall back to normal position by reason ofthe action of the springs 6, 14, and 18.

In Fig. 6 of the drawings I illustrate coacting upsetting-tools 27 28,which are adapted to be substituted for the form of tool shown in theother views of the drawings when it is desired to produce a pointedcalli, the angular faces of said tools 27 28 serving to upset thepointed end of a horseshoe-blank, so that a diametric line runningthrough the point thereof will lie at right angles to the main part ofthe shoe.

Having thus described my invention, what I claim as new, and desire .tosecure byLetters Patent, is-

1. In a device of the character set forth, the combination with astandard or upright, having an upsetting-tool thereon, of ahorseshoe-supporting bar pivoted thereto, a clamp on the upper end ofsaid supporting-bar and means for drawing said bar toward said uprightand bringing the projecting end of said horseshoe into engagement withsaid tool, s ubstantially as and for the purpose described.

2. In a device of the character set forth, the combination with anupright or standard, having an upsetting-tool in the upper end thereof,of ahorseshoe-supporting bar pivoted to said upright, a clamp adapted toengage the sides of the horseshoe-blank, a clamp for engaging the topsurface of said horseshoeblank, both located at the upper end of saidsupporting-bar and means for drawing said supporting-bar toward saidupright and bringing the projecting end of said horseshoe intoengagement with the upsetting-tool, substantially as, and for thepurpose described.

3. In a device of the character set forth, the combination with anupright or standard,

having an upsetting-tool at the upper end thereof, of ahorseshoe-supporting bar pivoted to said upright, a lever fulcrumed tosaid upright, engaging one end of a bolt attached to saidsupporting-bar, a foot-lever fulcrumed to said upright and projectingthrough a slot in said supporting-bar, a spring for normally holdingsaid foot-lever in its raised position, a rod pivoted to said foot-leverprojecting upwardly therefrom and formed with a head overlapping theupper end of said supportingbar and constituting a clamp for the topsurface of the horseshoe-blank, a sliding clamping-plate movable inguides in the upper end of said su pportin g-bar, and a lever fulcrumedto the side of said supporting-bar for operating the same, all arrangedsubstantially as and for the purpose described.

4. In a device of the character set forth, the combination with anupright or standard, having an inwardly-projecting ledge or shouldernear its upper end, a recess in the side of said standard, just abovesaid ledge or shoulder, an upsetting-tool fitting within said recessmade up of a plate having a projection on its rear surface and a springfor normally urging the upper end of said plate outwardly, of ahorseshoe-supporting bar pivoted to said upright or standard and havinga slot therein, a foot-lever fulcrumed to said upright and proj ectingthrough said slot, a spring for n ormally holding said foot-lever in itsraised position, a bolt passing through said upright and saidsupporting-bar having a head thereon which engages said bar and a nutupon its opposite end, a spring surrounding said bolt and engaging theinner surfaces of said upright and said bar, a lever fulcrumed on theoutside of said upright having bifurcated lower ends which surround saidbolt and engage the nut thereon, a rod pivoted to said foot-leverextending upwardly therefrom and formed with a head which overlaps theupper end of said supporting-bar and constituting a clamp for the topsurface of the horseshoe, a clampingplate slidingly mounted in the upperend of said supporting-bar, and a lever for operating said sliding platefulcrumed upon the side of said supporting-bar, substantially as and forthe purpose described.

In testimony whereof I have signed this yspecification in the presenceof two subscribing witnesses.
